1月31日Java班笔记作业
第一部分：笔记 First: SpinBox 背景：spinButton 控制了文本框的数字，所以不需要研究entry的数字限制形式
第一点：微调按钮（SpinButton）从GtkEntry继承，只能输入数字。 基本函数使用说明：
-
int gtk_spin_button_new_with_range(double min,double max,double step) 创建实例。min最小值、max最大值、单步变化值。double可以用来表示小数。 -
double gtk_spin_button_get_value(int spin_button) 获得double类型的值。
int gtk_spin_button_get_value_as_int(int spin_button) 以整数类型获得值，小数部分忽略。 void gtk_spin_button_set_value(int spin_button,double value) 设置值
学会：解决问题的能力。1 .查文档 2.google+baidu 3.FAQ
Second: ComboBox 第一点：GtkComboBoxText从GtkComboBox继承，GtkComboBoxText子类定义ComboBox. 基本函数：(使用说明) 第一步： int gtk_combo_box_text_new()创建一个ComboBoxText； 第二部： void gtk_combo_box_text_append(int combo_box,String id, String text) 附加一个文本，并且给它设定一个自定义id（String类型）。 第三步： String gtk_combo_box_get_active_id(int combo_box)得到选中行的自定义id gtk_combo_box_set_active_id(int combo_box,String active_id)设定自定义id等于active_id的项被选中 void gtk_combo_box_text_remove_all(int combo_box)清除所有内容 第四步 当选中一行的时候会发出“changed”信号 GTK.g_signal_connect(….);
Third: GTKIMAGE 第一点：GtkImage 可以分为三种方式加载图片资源，包括：磁盘文件（file），项目资源（resource），内置图片（STOCK），对应三个 家在函数gtk_image_set_from_file，gtk_image_set_from_resource，gtk_image_set_from_stock。
基本函数使用说明：
-
void gtk_image_set_from_file(int image, String filename)从文件全路径为filename的文件中加载图片。注意文件路径的转义问题，“\\”因为“\”有特殊含义，后面讲字符串会详细讲。 -
void gtk_image_set_from_resource(int image, String resName)从项目资源中加载图片，格式"com/rupeng/1.jpg"（其中com/rupeng表示com.rupeng包），不要以/开头，把资源放在src里面！！！
png可以背景透明，jpg、jpege压缩图片, Gif 动态图片
-
GTK.gtk_image_new_from_stock(GTK.GTK_STOCK_ABOUT, GTK.GTK_ICON_SIZE_LARGE_TOOLBAR); 从GTK的内置图片载入图片。
设置按钮图片一般是 GTK.GTK_STOCK* 设置大小的时候 利用GTK.GTK_ICON就可以弹出几个。。。
Fourth: GTKIMAGE的简单调研 /** * 把资源resName保存到临时文件夹，返回值为临时文件的全路径 * * @param resName * com/rupeng/a.mp3这样的格式，注意不以/开头 * @return */ public synchronized static String saveResourceToTemp(String resName) { // 如果resname之前释放到过临时文件，并且临时文件还存在，则不再重复释放，直接返回之前的文件，以提高性能 if (resourceCache.containsKey(resName)) //资源缓存中判断是否存在图片 { String cachedFileName = resourceCache.get(resName);//从资源缓存中获取图片 if (new File(cachedFileName).exists()) { return cachedFileName; } else { resourceCache.remove(resName); } } // 获取文件扩展名 String[] strs = resName.split("\."); //利用字符串的split函数 String extesion = strs[strs.length - 1]; //获取最后一个
InputStream inStream = GTK.class.getClassLoader().getResourceAsStream(resName);//ClassLoader.getSystemResourceAsStream(resName);
//通过反射机制 自动载入图片资源的ＩｎｐｕｔＳｔｒｅａｍ ！！！利用文件名字，这也是一个悬念
if (inStream == null)
{
throw new RuntimeException(“找不到资源” + resName);
}
try
{
//java 1.6后，运行在Windows下，如果启用了Guest账户，则由于createTempFile调用了SecureRandom 会卡5秒钟
//因此第一次运行createTempFile会非常慢
//参考：http://stackoverflow.com/questions/2608763/why-does-first-call-to-java-io-file-createtempfilestring-string-file-take-5-se
//File tempFile = File.createTempFile(“temp”, “.” + extesion);
//因此不用createTempFile，改用存到项目的restemp文件夹下
File resDir = new File(System.getProperty(“user.dir”), “gtk/temp”);// *.dll放的文件夹
if (!resDir.exists())
{
resDir.mkdirs();//创建临时文件夹
}
inStream.mark(Integer.MAX_VALUE); ／／不清楚作何用
String md5 = Utils.getMD5(inStream);//用md5值做文件名
inStream.reset();//指针复位到mark标记的位置，便于后面保存文件
// 如果不加扩展名，mci_send_command则无法识别文件类型
File tempFile = new File(resDir,md5+"."+extesion); //创建一个File
FileOutputStream outStream = new FileOutputStream(tempFile); //写出一个文件
Utils.copy(inStream,outStream); //把当前的图片资源靠背出去
inStream.close();
outStream.close();
resourceCache.put(resName, tempFile.getAbsolutePath());//放到绝对路径下
return tempFile.getAbsolutePath(); //最终返回图片
} catch (IOException e)
{
throw new RuntimeException(e);
}
}
/**
* 从java资源中加载资源图片生成image。不是gtk提供的native方法
*
* @param resName
* @return
*/
public static int gtk_image_new_from_resource(String resName)
{
return gtk_image_new_from_file(saveResourceToTemp(resName));
复制代码
Fifth: TextView 背景：先前entry是当行文本框 TextView基本函数使用说明： 第一步： 创建多行文本夹 int gtk_text_view_new()创建多行文本 第二步： 进行接本的设置 void gtk_text_view_set_wrap_mode(int text_view,int wrap_mode) 设置自动换行模式。wrap_mode可选值：GTK_WRAP_NONE(不自动换行)；GTK_WRAP_CHAR(在任意字符换行)；GTK_WRAP_WORD(保持单词完整性换行，)；GTK_WRAP_WORD_CHAR (尽量保持单词完整性，实在不行也可以在任意字符换行)
第三步： 添加文字和读取文字 读取文字 String text = GTK.gtk_text_buffer_get_text(textbuffer); 添加文字 GTK.gtk_text_buffer_set_text(textbuffer, loveWords) 额外的标注： 一般第三步采用的方式适合比较小的String，对于较大的情况可以再加一个TextIter类似可以在多行文本或者对话框 添加一个滚动条ScrolledBar TextIter使用说明： 1：TextIter是对TextBuffer遍历的遍历器。 2： int gtk_text_iter_new()创建一个空的TextIter，使用完后用gtk_text_iter_free(int iter)释放。 3： void gtk_text_buffer_get_start_iter(int buffer,int iter)用buffer这个TextBuffer的开始位置去初始化iter这个TextIter（开头插入 或者用backward指针 向后读） void gtk_text_buffer_get_end_iter(int buffer, int iter)用buffer这个TextBuffer的结束位置去初始化iter这个TextIter（结尾插入 或者也可以用forward指针 向前读） (*)用gtk_text_buffer_get_iter_*系列方法移动迭代器的位置。 4. void gtk_text_buffer_insert(int buffer, int iter,String text)在buffer这个TextBuffer的iter这个TextIter的当前位置插入文本text
5 gtk_text_iter_free(int iter) 释放textIter资源
Sixth: Cairo 1： 画布板 是一个框架，一般仅仅在第一步创建的时候使用 GTK.gtk_drawing_area(); 2： 画布环境(Cairo_t)，缺不了，在java的Cairo中直接在GTK.g_signal_connect中的draw时间中使用，对应execute函数的 eventsData 即使Cairo_t ,基本上每一个Cairo函数都少不了ct 3: com.rupeng.gtk4j.Cairo简化了绘画的步骤，一般是 3.1 设置画笔的大小 Cairo.cairo_set_font… 3.2 设置画笔的颜色 3.3 Cairo.cairo_move_to(cr…) 3.4 Cairo.cairo_line_to(cr,,,)画直线 3.5 Cairo.cairo_arc(cr,…)画圆弧 记住最好是分段绘制也就是每画一个加入 GTK.gtk_stroke() 或者GTK.gtk_fill(); 3.6 Cairo.cairo_rec 画矩形 3.7 文字的绘制 3.7.1 //画文字 3.7.2 Cairo.cairo_move_to(eventData, 180, 260); 3.7.3 Cairo.cairo_set_source_rgb(eventData, 0.4, 0.3, 0.2); 3.7.4 Cairo.cairo_set_font_size(eventData, 16); 3.7.5 //选择文字类型 3.7.6 Cairo.cairo_select_font_face(eventData, “宋体”, Cairo.CAIRO_FONT_SLANT_ITALIC, Cairo.CAIRO_FONT_WEIGHT_BOLD); 3.7.7 Cairo.cairo_show_text(eventData,“三毛的自画像”); 3.7.8 //Cairo.cairo_stroke(eventData); //不需要这句话也可以
